“采矿无痕” 晋能控股三元煤业开创煤炭开采新模式

Core Viewpoint - The company has successfully implemented two green mining technologies, namely paste filling mining and roof layer grouting filling mining, which not only maximize coal resource recovery but also effectively utilize solid waste, establishing a new model of "mining without a trace" [1][3][8]. Group 1: Green Mining Technologies - The paste filling mining technology uses a mixture of gangue, cement, fly ash, and water to support the overlying rock layer, ensuring minimal ground subsidence while recovering coal resources [4]. - The roof layer grouting filling mining technology addresses specific geological conditions, allowing for efficient coal extraction while controlling structural deformation [6]. - As of now, these technologies have released 2.4 million tons of coal resources and processed 160,000 tons of solid waste, with plans to increase green mining capacity from 1.4 million tons per year to 1.8 million tons by the end of 2027 [6][7]. Group 2: Environmental and Economic Impact - The implementation of these technologies has transformed the mining area into a "garden-style mine" with over 60% greening rate, significantly improving the ecological environment [1][3]. - The company has received recognition for its innovative practices, with plans to promote these green mining techniques across other coal mines, enhancing the overall industry standards [7][9]. - The use of solid waste as a substitute for cement in the paste filling process aligns with low-carbon utilization goals, contributing to the dual carbon targets [7][8]. Group 3: Industry Standards and Future Prospects - The company is actively involved in setting industry standards for green mining practices, which will facilitate the broader adoption of these technologies across the sector [9][11]. - The innovations at the company serve as a benchmark for other mining enterprises, promoting a shift from resource-intensive to technology-driven mining practices [11].
